7 Claims.

This invention relates to new and useful improvements in operatinghandles and more particularly to handle assemblies for operatingandlocking jalousiesand Venetian windows in adjusted positions.

v One object of the invention is to provide an improved handle foroperating ajalousie and Venetian window and of such construction thatthe handle may be locked readily in any desired gfoisigion topreventoperation of the jalousie or Another obiect of the invention is toprovide an improved handle assembly for operating and locking jalousiesand Venetian windows in adjusted positions which includes a pivotedrotatable lever and cam means rotatable with and actuated by pivotalmovement of the lever for moving conical surfaces into engagement so asto lock said lever against rotation, together with nmegns for connectingsaid lever to an operating A particular object of the invention is toprovide an im roved handle assembly, of the character described, whichincludes an angular member journaled in and extending through a supportfor connecting the lever to an operating link whereby the member isrotated by said lever so as to reciprocate the link and functions as abearing for said lever.

A further object of the invention is to provide an improved handleassembly, of the character described, wherein the angular member has ashoulder overlying the inner surface of the support and disposed in thebore of a base plate secured to said inner surface whereby said memberis confined therebetween and isinsertable inwardly of said support, thelever being connected to said member by an element rotatablyand'slidably mounted in said bore. ,7

A construction designed to carry out the invention will be hereinafterdescribed together with other features of the invention.

The invention will be more readily understood from a reading of thespecification and byreference to the accompanying drawing, wherein anexample of the invention is shown, and wherein:

Fig. 1 is an exploded, perspective view of a handle assembly constructedin accordance with the invention, I

Fig. 2 is an enlarged, transverse; vertical, sectional view of thehandle assembly, shown In the drawing, the numeral lfl designates ahandle assembly for operating or tilting or locking the louvers of ajalousie or Venetian window (not shown) in open, closed or intermediatepositions. The assembly I includes an angular arm or member H, aconnecting element or spindle mounted on a frame member and in itsunlocked position, and Fig. 3 is a view, similar to'Fig. 2, showing thelocked position of the assembly.

' spindle.

l2, a base or an escutcheon plate l3, a cam member or ring l4 and anactuating lever 15 which is adapted to be pivotally connected to thespindle by a transverse pin l6. As shown in Figs. 2 and 3, the plate 13is substantially fiat and rectangular and is adapted to be secured inoverlying relation to the inner surface of a support or frame member H,which is angular in crosssection, by suitable screws l8 and nuts [9. Anoperating link is pivotally connected by a rivet 2! or other suitablemeans to the lateral portion or leg 22 of the arm II.

It is noted that the spindle [2, plate l3, cam ring I4 and lever I5 areshown in the co-pending application of Sanderlin and Grant filed July18, 1949, Serial No. 105,384. A transversely-extending boss 23 is formedon the plate and has a cylindrical opening or bore 24 for receiving theThe major portion of the bore 24 is tapered or flared outwardly towardthe inner side of the plate so as to provide a conical counterbore orwedge surface 25. 'An-annular recess 26 is provided at the extremity ofthe conical counterbore adjacent'the inner side of the plate. Thespindle l2, while generally cylindrical, has flat sides 28 and is of alength considerably greater than the length of the bore 24, itscounterbore, and recess, so as to project beyond the boss 23 whenengaged in said bore. A conical enlargement or wedgesurface 21,complementary to theconical counterbore, is formed on the inner endportion of the spindle for coacting with said counterbore to lock orgrip said spindle against rotation. Intermediate the conical andflattened surfaces 21' and 28, a circular portion 29 is provided forcoacting with the cylindrical bore 24 in maintaining the spindle inaxial alinernent with said bore. It is preferable to round or bevel theouter end of the spindle as shown by the numeral 30. A polygonal socket3] is formed in the inner end of the spindle (Fig. 3) V The leverincludes a curved handleportion 32 and anenlarged head 33 having a deep,rectangular recess or socket 34 complementary. to the outer endportionlof the spindle, said spindle portion being confined in thesocketby the connecting pin l6. Limited pivotal movement of the leverabout the axis of the pin and relative to the spindle is permitted by aslot 35 cut in the wall of the head 33 opposite the handle portion 32. Apair of inwardly-directed, parallel ears or extensions 36 are formed bythe provision of the recess and the slot and the inner ends of theseears are curved or bevelled outwardly and longitudinally to provide camsor cam faces 31 for coacting with the cam ring 14.

Ihe cam ring is preferably circular externally and has an elongateopening or slot 38 through which the flattened portion 28 of the spindleextends, whereby said ring is rotatable with said spindle; the slotbeing generally complementary to the cross-sectional shape of thespindle. It is noted that the slot 38 is of a length greater than thelargest diameter of the spindle portion 28 so that the ring may slide ormove transversely relative to the lever and spindle. Arcuate, undercutcams or cam faces 39 are formed in the outer end surface of the ringparallel to the longitudinal axis of its slot for coacting with the camfaces 31 to draw the oonicalwedge surfaces 25 and 21 into tightengagement. By ofI- setting the slot longitudinally toward the inner orhead end of the lever, the. low points of the cam faces 39 move past thehigh points of the cam faces 31 upon inward swinging of the lever so asto increase the locking action of said-faces (Fig. 3). Outward swingingof the lever moves the cam faces into registration so as to disengagethe conical wedge surfaces (Fig. 2).

The arm ll includes a substantially cylindrical body portion 40 carryingthe lateral portion or leg 22 and having an enlarged annular bearing. 4|which is adaptedto be journaled in an opening 42 formed in the supportH. An enlargement in the form of a radial shoulder. or flange 43 isformed externally of the bearing t! for engaging the inner 'surfaceof'the support in overlying relation to the opening 42. The enlargement 3-3is disposed within the recesslt of the plate 13 so as to be confinedbetweenv said plate and the support. A polygonal stud or shank M isformed onthe inner extremity, of the body G for slidable engagement withthe socket 3|.

In operation, thelever is swung outwardly to unlock the spindle andpermit rotation thereof by turning of said lever. The camfaces. 3'! and53' are moved into registration by outward swinging of the lever andthecam ring M is slid toward the outer end of said lever (Fig. 2). Ihipermits inward movement of the spindle and disengagement of the conical.surfaces 25 and 2?, whereby thelever, spindle and angular arm may befreely rotated to swing the leg 22 of said arm and reciprocate the linkv20.. Whenever it is desired tolocklthe. linkin an adjusted position,which may be-closed', open or intermediate positions, the lever is swunginwardly (Fig. 3). It is noted that the. ring 14' has a transversesliding movement and that the arcs, on which the camfaces 31 and 39 arestruck, do not have their centers in the bolt. pin. IS on which thelever 15 swings. In the locked position, the handle is swung inwardlyand the ring I4 is moved upwardly (Fig. 3); thus,.fastening the partsagainst rotation; but when the handle is swung outwardly, the cam ringis moved downwardly (Fig. 2). thereby'freeingthe parts for rotation. Dueto the registration of the cam faces, the camring. slides toward theinner end of the lever and into axial alinement with the spindle- Uponcontinued inwardswinging of the lever, the cam faces31 ri'd'e" slightlypast registrationwith the cam faces soa s to force the spindle outwardlyand tightly engage the coni- 4 cal surfaces of the bore and spindle. Inthis manner, the spindle is locked against rotation so as to maintainthe link in the desired position.

It is noted that the length of the conical surface 25 is greater thanthe length of the conical surface 21 of the spindle so as to permitmovement of the spindle relative to the arm. As shown in Fig. 3,.thesocket 3| and shank 44 provide a slidable connection between the arm andspindle so as to permit relative longitudinal movement of said spindle.The bearing 4| serves to support the spindle for maintaining the same inaxial alinement with the bore 24. Due to the provision of the shoulder43, the arm H is confined by the coaction of the base plate l3 and thesupport I! and is insertable inwardly of said support. Y

The foregoing description of the invention is explanatory thereof andvarious changes in the size, shape and materials, as well as in thedetails of the illustrated. construction may be made, within the scopeof theappended claims, without departing from the spirit of theinvention.
